Description:Current issues are now on the Chicago Journals website. Read the latest issue.The International Journal of Plant Sciences has a distinguished history of publishing research in the plant sciences since 1875. IJPS presents high quality, original, peer-reviewed research from laboratories around the world in all areas of the plant sciences. Topics covered range from genetics and genomics, developmental and cell biology, biochemistry and physiology, to morphology and anatomy, systematics, evolution, paleobotany, plant-microbe interactions, and ecology. IJPS does NOT publish papers on agriculture or crop improvement. In addition to full-length research papers, IJPS publishes review articles, including the open access Coulter Reviews, rapid communications, and perspectives. IJPS welcomes contributions that present evaluations and new perspectives on areas of current interest in plant biology. IJPS publishes nine issues per year and regularly features special issues on topics of particular interest, including new and exciting research originally presented at major botanical conferences.

There are no costs for publishing in IJPS. The journal does not assess page charges, and color figures that enhance the quality of papers are provided free of charge. Manuscript evaluation times vary, but decisions on peer-reviewed papers typically take 5–6 weeks.

The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

Phylogenetic models of the Clusiaceae have so far been based on morphological data only. As an additional source of phylogenetic information, the chloroplast gene rbcL was sequenced for 26 species, representing all available genera of Clusiaceae. The DNA data were analyzed cladistically together with previously published sequences. The results show that the aquatic family Podostemaceae is nested inside Clusiaceae as the sister group of subfamily Hypericoideae or tribe Hypericeae. The subfamilies Kielmeyeroideae and Clusioideae, as delimited in recent morphology‐based classifications, are largely supported as monophyletic. The sole exception is Clusiella, which links with Kielmeyeroideae rather than with Clusioideae. We conclude that pollination by resin‐collecting bees arose independently in Clusiella and the Clusioideae: Clusieae.
